I think you'd be surprised how much an ENTP can care about something whilst still being willing to let it go for now. Perhaps it's the pragmatism of the NT that tells me it's absolutely pointless trying to discuss it and assesses that it will achieve nothing, and so I'm able to override the emotional feeling, the frustration or whatever, for the sake of logical expediency. I think that perhaps the ENFP's idealism is what's the real block to them being able to do this, rather than to say that the reason the ENTP can is that they just don't really care.
I'm not sure if there's a typo in there somewhere, cos that end part doesn't seem to really scan...? Do you mean "...that ENTPs want to stay within conflict"?
My experience with my brother is that it's quite often because I really do care about something and it is important to me, I'm the one insisting that this isn't something that should be glossed over or moved past without further examination, but the minute he hears the emphasis in my voice he's interpreting it as aggression and just switching off, that's when the whole frustration levels in me hit the roof, because he stops listening at all to anything I'm saying, instead focusing on the strength of feeling/frustration that's coming out in my tone of voice and trying to get me to drop it because it feels like conflict to him. I see it as rather ironic that he's the one
causing it to seem like conflict, because all I wanted was a calm discussion and he's said that he likes to see that someone really cares about something - and yet here we are, there's emphasis in my voice that's because I care, and that's his signal to stop listening and try to shut me up! And it's him refusing to listen that gets me actually angry and telling him to ffs listen, cos all I want to do is say what I've got to say and for him to listen and understand. And it's doubly ironic because when I don't want to open up he's insisting that I should, and here I am, opening up, really caring, about something really important to me, and he's trying to get me to shut up and drop it because it all feels a bit too much like conflict to him!

:steam:
When it comes to a group situation, where I can sense through Ne-Fe that although this or that issue is important and needs to be discussed, insisting on doing it NOW will not achieve the affect that my dear little idealist wants it to achieve and will, in fact, cause a lot of resentment and nobody will really take on the issues at hand. That's why I'd advocate moving on, and not because I simply don't give a shit.
I think that's what seems to me the difference with the ENxP's - I can see the same shit you do and I can have feelings about it too, but somehow I'm able to override my own feelings about it for the sake of expediency, efficacy and group dynamics, whereas you're oblivious to those things and just stuck in the "but this is how I FEEL" situation, so you end up futilely ranting to an unsympathetic and unlistening audience at an inappropriate time, achieving nothing.
I don't mean personally you, just sorta generally you, as in 'one' lol
